GstBaseTransform missing frames
 
|
Hi guys,
We have problem with missing some frames due to finishing pipeline before we done with processing. We have inherited our elements from GstBaseTransform. Our elements do processing in their own threads in parallel. According to documentation (https://gstreamer.freedesktop.org/documentation/base/gstbasetransform.html#GstBaseTransformClass::generate_output) we can return GST_BASE_TRANSFORM_FLOW_DROPPED and it is fine. So, when filesrc reach end of file and send EOS we didn't finished processing yet, but due to EOS pipeline finishes and we are losing some frames that are in processing. We would like to keep processing in our own threads and do not lose frames when pipeline finishes. Is there any convenient way to make pipeline wait until we finished? or maybe we can return something different instead of "drop" status? Thank you in advance!

So, I can block pipeline on EOS, finish processing, push frames, unlock EOS event to let it finish pipeline. Am I correct? If so, thanks a lot! From: gstreamer-devel <[hidden email]>

By the way, why should I report latency? From: Abdumuminov, Umedzhon So, I can block pipeline on EOS, finish processing, push frames, unlock EOS event to let it finish pipeline. Am I correct? If so, thanks a lot! From: gstreamer-devel <[hidden email]>
